Summary:A three-dimensional few-layer reduced graphene oxide-wrapped mesoporous Li4TisO12 （m-LTO@FL- RGO） electrode is produced using a simple solution fabrication process. When tested as an anode for Li- ion batteries, the m-LTO@FL-RGO composite exhibits excellent rate capability and superior cycle life. The capacity of m-LTO@FL-RGO reaches 165.4 mA h g 1 after 100 cycles between I and 2.5 V at a rate of 1 C. Even at a rate of 30 C, a high discharge capacity of 115.1 mA h g 1 is still obtained, which is three times higher than the pristine mesoporous Li4TisO12 （m-LTO）. The graphene nanosheets are incorporated into the m-LTO microspheres homogenously, which provide a high conductive network for electron transportation.
